Technical Field

[0001] This utility model relates to the field of angle grinder technology, specifically to an automatic dust collection and removal device for angle grinders. Background Technology

[0002] An angle grinder is a mechanical device used for cutting and grinding. When in use, the grinding wheel rotates at high speed to grind or cut the workpiece. However, in this process, a large amount of dust is generated. The dust that splashes out may enter the respiratory tract of the workers, thus affecting their health.

[0003] Currently, angle grinders are generally equipped with covers to block dust from splashing. However, these covers are usually fixed structures, while the angle of the grinder changes during operation. This means the cover cannot effectively block the splashing dust, and it lacks a dust suction function, causing the dust to eventually fall outside, thus affecting the dust removal effect. Summary of the Invention

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an automatic dust removal device for an angle grinder, comprising a cover 1. An arc-shaped flange 2 is formed by bending the central hole of the cover 1. A clamp 3 is provided inside the arc-shaped flange 2, and a connecting groove 4 is provided on the outer surface of the clamp 3. A connecting strip 12 is installed on the inner side of the arc-shaped flange 2, directly opposite the connecting groove 4. The connecting strip 12 is slidably disposed in the connecting groove 4. Screw holes penetrating the connecting strip 12 and the arc-shaped flange 2 are provided on the connecting strip 12 and the arc-shaped flange 2. A screw 5, threaded into the screw holes, positions the rotated cover 1 on the clamp 3. An installation port is provided on the outer surface of the cover 1, and a dust suction hood 7 is provided in the installation port. A dust suction pipe 11 is installed at one end of the dust suction hood 7. One end of the dust suction pipe is connected to a vacuum cleaner via a flexible hose, enabling suction to be generated on the cover, thereby absorbing dust.

[0023] In this embodiment, the dust collection hood 7 is provided with fixing plates 9 on both sides, one end of each fixing plate 9 is installed on the cover 1, and the inner side of each fixing plate 9 is provided with a positioning groove communicating with the inner cavity of the cover 1. The dust collection hood 7 is provided with positioning plates 8 on both sides, and the positioning plates 8 are slidably disposed in the positioning grooves. The outer side of each positioning plate 8 is provided with a first screw hole, and the outer side of each fixing plate 9 is provided with a second screw hole opposite to the first screw hole. The opposite first screw hole and second screw hole are threaded with a hand-tightening bolt 10.

[0024] After the hand-tightened bolt is removed from the first screw hole, the dust cover can be removed outward from the mounting opening, making it easy to replace and clean.

[0025] In this embodiment, the connecting strip 12 is arranged in an arc shape, and the degree of arc of the connecting strip 12 matches the degree of arc of the clamp 3. The cross-sections of the connecting strip 12 and the connecting groove 4 are both arranged in a "T" shape, so that the cover can only rotate along the connecting groove. The T-shaped structure prevents the connecting strip from coming off the connecting groove. The clamp is made of metal material, which increases the firmness and further prevents the connecting strip from coming off.

[0026] In this embodiment, the surface of the cover 1 is provided with an arc-shaped groove opposite the screw hole. One end of the screw 5 is in contact with the inner wall of the connecting groove 4, and the other end of the screw 5 extends through the arc-shaped groove to the outside of the cover 1 and is equipped with a handle 6.

[0027] In this embodiment, the opening end face of the dust hood 7 is set with an arc-shaped structure, and the opening end face of the dust hood 7 is flush with the inner ring surface of the cover body 1, so that dust can smoothly enter the dust hood along the inner ring covered, avoiding obstruction.

[0028] In this embodiment, the inner cavity of the dust hood 7 is narrowed inward at the end facing the dust suction pipe 11, so that the incoming dust can be concentrated inward at the narrowed end, thereby entering the dust suction pipe more smoothly.

[0029] In this embodiment, the length and width of the dust hood 7 match the length and width of the mounting opening, which increases the stability of the dust hood after installation and avoids swaying in the mounting opening.

[0030] The cover is fixed to the angle grinder by clamps. When the operating angle of the angle grinder changes, the screw can be rotated by holding the lever, so that one end of the screw can be moved away from the inner wall of the connecting groove. At this time, the cover can rotate in a ring shape along the connecting groove until the cover rotates to the side where dust splashes, so as to block dust more efficiently. After the angle is determined, the screw is rotated in the opposite direction so that one end of the screw abuts against the inner wall of the connecting groove. The positioning operation of the cover is completed by squeezing and friction.

[0031] During the cutting or grinding process of an angle grinder, dust will enter the dust collection hood. The suction power generated by the vacuum cleaner acts on the dust collection hood, causing the dust that has entered the hood to quickly pass through the dust collection hood and suction pipe into the vacuum cleaner, greatly reducing the amount of dust and increasing the safety of construction.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
